The bug is in your setup.
Configure your secondaries with master entries pointing to the IP the
the primary uses to send the notifies and it will work, regardless
what the NS zone records show. This however assumes that the primary
will also honor AXFR requests from the secondaries on that IP.

You could also do a small patch to the bind code to allow every IP
to send notifies. Last time I checked it was a three liner or so.
However such a patch will probably make you open to DoS attacks
very easily.
I thought of adding a "allow-notify" option, but solved it with the
above setup, as that was the quicker and IMHO cleaner solution.
